The Phase Stability and the Electrical Properties of the System La($Ni_{1-x}Cu_$chi$$)$O_3$

ABSTRACT

The phase stability and the electrical properties of La(Ni1-$chi$Cu$chi$)O3 (X=0.2, 0.4, 0.6, 0.8) have been investigated. The single phases were observed in the compositions of X=0.2, 0.4, and these single phases were stable up to 87$0^{circ}C$ and 95$0^{circ}C$ respectively. The electrical properties of these single phase samples showed metallic behavior similar to LaNiO3 from room temperature to the temperature at which the phase was stable.
